Description

Technical Field

[0001] This utility model relates to the field of cap beam technology, and more specifically to cap beams for prefabricated buildings. Background Technology

[0002] A capping beam is a continuous reinforced concrete beam installed on top of the perimeter support structure of an excavation pit. Its main function is to connect all the pile foundations together to prevent collapse at the top edge of the pit or shaft. Most existing capping beams are formed by concrete pouring. Construction of a capping beam involves several steps: excavating the foundation trench, removing pile heads, installing reinforcing bars, installing formwork, pouring concrete, and removing the formwork. During formwork installation, several formwork panels need to be installed on both sides of the foundation trench. Two corresponding formwork panels also need to be in contact with each other through two uprights inserted into the soil beside the foundation trench. A horizontal bar connects the two uprights, increasing the stability of the formwork and preventing misalignment caused by the pressure of the concrete during pouring.

[0003] When inserting the uprights into the soil, most of the time it is done manually with the help of auxiliary tools to hammer the uprights into the soil. This often results in the uprights not being able to make complete contact with the formwork, which leads to a gap between the formwork and the uprights. When pouring concrete, the pressure of the concrete causes the formwork to shift or tilt, which in turn affects the stability of the entire support structure. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a capping beam for prefabricated buildings to solve the problem that the uprights inserted into the soil cannot make complete contact with the template in the above-mentioned background art.

[0005] This utility model provides the following technical solution: a capping beam for prefabricated buildings, including a template, two uprights and a crossbar, and further including an adjustment component and two sets of limiting components. The template is set on both sides of the foundation pit, and adjacent templates are interlocked. The crossbar is set on the top of the templates on both sides. The adjustment component is set inside the crossbar. The two sets of limiting components are connected to the adjustment component. The adjustment component allows one set of limiting components to move closer to the other set of limiting components. The two uprights are respectively connected to the two sets of adjustment components. Each set of limiting components is provided with a fixing component. Each of the two uprights has several fixing holes arranged in a row. The fixing component allows the uprights to be fixedly connected to the limiting components.

[0006] Furthermore, the adjustment assembly includes a lead screw, a turntable, a slot, and two connecting blocks. The slot is opened on the crossbar. The turntable is rotatably connected to one end of the crossbar. The end of the crossbar connected to the turntable is open. The lead screw is set in the slot and fixedly connected to the turntable. One of the two connecting blocks is sleeved on the lead screw, and the other end is fixedly installed in the slot. The connecting block sleeved on the lead screw slides in conjunction with the slot.

[0007] Furthermore, both of the aforementioned limiting components include an annular block, a connecting hole, and a limiting hole. The two annular blocks are respectively fixedly connected to the corresponding connecting blocks, and the two arc-shaped blocks are respectively sleeved on the corresponding uprights and slidably engaged with the corresponding uprights. The connecting hole coincides with one of the plurality of fixing holes, and the limiting hole is opened on the annular block.

[0008] Furthermore, the fixing component includes a limiting rod, a pull rod, and a spring. The limiting rod, pull rod, and spring are all disposed in the connecting hole. The limiting rod is slidably engaged with the connecting hole. One end of the pull rod is fixedly connected to the limiting rod, and the other end passes through the annular block and is slidably engaged with the annular block. The spring is sleeved on the pull rod, with one end of the spring fixedly connected to the inner wall of the connecting hole and the other end of the spring contacting the limiting rod.

[0009] Furthermore, each of the two pull rods has a disc fixedly installed at one end of its corresponding annular block, and a fixing rod is fixedly installed on the side of each of the two discs.

[0010] Furthermore, the bottoms of the two uprights are tapered.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, workers use auxiliary tools to drive the uprights vertically into the soil along the annular block and the template. The annular block limits the position of the uprights, thereby ensuring that the uprights are in complete contact with the template and improving the stability of the structure.

[0013] 2. In this utility model, the worker pulls a disc, causing the disc to move the fixed rod, pull rod, and limit rod. This causes the limit rod to compress the spring again, causing the fixed rod to come out of the limit hole. The worker then rotates the disc, causing the fixed rod, pull rod, and limit rod to rotate synchronously. At this point, the worker stops pulling the disc, and the spring rebounds, causing the limit rod, pull rod, disc, and fixed rod to move synchronously. This allows one end of the limit rod to enter the fixed hole from the connecting hole. At this point, the upright and the annular block are connected and fixed, eliminating the need for workers to use auxiliary tools to tighten bolts for installation, thus improving the efficiency of the installation.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 5 The present invention will be further described below.

[0022] This utility model discloses a capping beam for prefabricated buildings, including a template 1, two uprights 2 and a crossbar 3, as well as an adjustment component 4 and two sets of limiting components 5. The template 1 is set on both sides of the foundation pit, and adjacent templates 1 are interlocked. The crossbar 3 is set on the top of the templates 1 on both sides. The adjustment component 4 is set inside the crossbar 3. The two sets of limiting components 5 are connected to the adjustment component 4. The adjustment component 4 can make one set of limiting components 5 move closer to the other set of limiting components 5. The two uprights 2 are respectively connected to the two sets of adjustment components 4. Each set of limiting components 5 is provided with a fixing component 6. Each upright 2 has several fixing holes 7, which are arranged in a row. The fixing component 6 can fix the uprights 2 to the limiting components 5.

[0023] In this implementation plan, during installation, workers place template 1 on both sides of the foundation pit, insert it into the soil beside the pit, and determine the distance between the templates 1 on both sides. Adjacent templates 1 are interlocked. Workers place the reinforcing cage between the templates 1 on both sides. At this time, workers place the horizontal bar 3 on the templates 1 on both sides, with the horizontal bar 3 contacting the top of the templates 1 on both sides. The horizontal bar 3 is then connected to the top of the templates 1 on both sides by bolts. The fixed upright 2 abuts against one side of the template 1. At this time, workers use the adjusting component 4 to move one set of limiting components 5 closer to another set of limiting components 5, and one upright 2 moves closer to another upright 2, so that the two uprights 2 contact the corresponding template 1 surfaces. At this time, workers release the uprights. 2. Fixing with limiting component 5: At this time, the staff uses auxiliary tools to drive the two uprights 2 into the soil, so that the uprights 2 are driven into the soil along the surface of the corresponding template 1, thereby ensuring that the uprights 2 are always in contact with the template 1. The uprights 2 can make the template 1 more stable. At this time, the staff pours the cement mortar between the two templates 1. When the pouring is completed, the poured cement mortar is formed. At this time, the staff will loosen the bolt connection between the horizontal bar 3 and the two templates 1. At this time, the staff will remove the horizontal bar 3 from the template 1. The horizontal bar 3 drives the two uprights 2, the adjusting component 4, the limiting component 5 and the fixing component 6 to move synchronously, so that the two uprights 2 are pulled out of the soil. At this time, the staff will remove the templates 1 that are interlocked from the formed crown beam.

[0024] Specifically, the adjustment component 4 includes a lead screw 401, a turntable 402, a slot 403, and two connecting blocks 404. The slot 403 is opened on the crossbar 3. The turntable 402 is rotatably connected to one end of the crossbar 3. The end of the crossbar 3 connected to the turntable 402 is open. The lead screw 401 is set in the slot 403 and is fixedly connected to the turntable 402. One of the two connecting blocks 404 is sleeved on the lead screw 401, and the other end is fixedly installed in the slot 403. The connecting block 404 sleeved on the lead screw 401 is in sliding fit with the slot 403.

[0025] In this implementation scheme, when two uprights 2 need to contact two corresponding templates 1, the worker places the horizontal bar 3 on top of the two corresponding templates 1 and connects the horizontal bar 3 to the top of the two templates 1 with bolts. At this time, the worker will rotate the turntable 402, which will drive the lead screw 401 to rotate. Because of the limiting of the slot 403, the connecting block 404 sleeved on the lead screw 401 moves along the slot 403 to the other connecting block 404. When the worker rotates the turntable 402 in the opposite direction, the connecting block 404 sleeved on the lead screw 401 moves away from the other connecting block 404.

[0026] Specifically, each of the two limiting components 5 includes an annular block 501, a connecting hole 502, and a limiting hole 503. The two annular blocks 501 are fixedly connected to the corresponding connecting blocks 404, and the two arc-shaped blocks are respectively sleeved on the corresponding uprights 2 and slidably engaged with the corresponding uprights 2. The connecting hole 502 coincides with one of the several fixing holes 7, and the limiting hole 503 is opened on the annular block 501.

[0027] In this embodiment, in the initial state, the connecting hole 502 and one of the fixing holes 7 are at the same level. The fixing component 6 enters the fixing hole 7 from the connecting hole 502, so that the upright 2 is connected to the annular block 501. When the connecting block 404 sleeved on the threaded rod 401 moves, it drives the annular block 501 and the corresponding upright 2 to move synchronously. When the fixing component 6 no longer connects the upright 2 to the annular block 501, the workers use auxiliary tools to drive the upright 2 into the soil. Because of the limitation of the annular block 501, the support can only enter the soil along the annular block 501, thereby ensuring that the upright 2 is in complete contact with the template 1, thereby improving the stability of the structure. After the upright 2 is inserted into the soil, the connecting hole 502 coincides with one of the fixing holes 7. At this time, the workers will connect the annular block 501 to the upright 2 through the fixing component 6, and then the workers will pour the concrete.

[0028] Specifically, the fixing component 6 includes a limiting rod 601, a pull rod 602, and a spring 603. The limiting rod 601, pull rod 602, and spring 603 are all disposed in the connecting hole 502. The limiting rod 601 is slidably engaged with the connecting hole 502. One end of the pull rod 602 is fixedly connected to the limiting rod 601, and the other end passes through the annular block 501 and is slidably engaged with the annular block 501. The spring 603 is sleeved on the pull rod 602. One end of the spring 603 is fixedly connected to the inner wall of the connecting hole 502, and the other end of the spring 603 contacts the limiting rod 601. A disc 8 is fixedly installed on one end of each pull rod 602 that passes through the corresponding annular block 501. A fixing rod 9 is fixedly installed on the side of each of the two discs 8.

[0029] In this embodiment, in the initial state, the connecting hole 502 coincides with one of the fixing holes 7, and one end of the limiting rod 601 enters the corresponding fixing hole 7. At this time, the annular block 501 is connected and fixed to the upright 2. When it is necessary to insert the upright 2 into the soil, the worker will pull the disc 8. The disc 8 drives the pull rod 602 and the fixing rod 9 to move. The pull rod 602 drives the limiting rod 601, so that the limiting rod 601 enters the connecting hole 502 from the fixing hole 7. The limiting rod 601 compresses the spring 603. At this time, the worker... The operator rotates the disc 8, which drives the fixed rod 9, pull rod 602, and limit rod 601 to rotate synchronously. The fixed rod 9 rotates to the limit hole 503 area. At this point, the operator stops pulling the disc 8, and the spring 603 rebounds, causing the limit rod 601, pull rod 602, disc 8, and fixed rod 9 to move synchronously. The fixed rod 9 then enters the limit hole 503. At this point, the limit rod 601 is located within the connecting hole 502. The upright 2 is no longer fixed to the annular block 501. The operator will then use an auxiliary... The auxiliary tool drives the upright 2 vertically into the soil along the annular block 501 and the template 1. The annular block 501 limits the position of the upright 2, ensuring complete contact between the upright 2 and the template 1, thereby improving the stability of the structure. When the upright 2 is fully inserted into the soil, the connecting hole 502 coincides with one of the fixing holes 7. At this time, the worker pulls the disc 8, causing the disc 8 to move the fixing rod 9, the pull rod 602, and the limiting rod 601. This causes the limiting rod 601 to compress the spring 603 again, causing the fixing rod 9 to move out of the limiting hole 501. Once the disc 8 is rotated, the worker rotates the fixed rod 9, the pull rod 602, and the limit rod 601. The worker then stops pulling the disc 8, and the spring 603 rebounds, causing the limit rod 601, pull rod 602, disc 8, and fixed rod 9 to move synchronously. This allows one end of the limit rod 601 to enter the fixed hole 7 through the connecting hole 502. At this point, the upright 2 and the annular block 501 are connected and fixed, eliminating the need for workers to use auxiliary tools to tighten bolts for installation, thus improving installation efficiency.

[0030] Specifically, the bottoms of the two uprights 2 are tapered.

[0031] In this implementation plan, the bottom of the pole 2 is tapered, which makes it easier to drive the pole 2 into the soil.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
